Desiccant substitute

[davidhall]

Can water softener salt be a substitute for desiccant (a or c) in a desi-dri system. Or is there anything thing else that can be used instead of the expensive propitiatory desi-dry desiccant from NATCO.

Thanks,
David Hall

There are other delequesent-drier salts that are slightly less expensive than Des-Dri, but they're not cheep either. You can use water-softener salt if you don't care about it working (it won't work).

Dessicant is used because of it's good drying properties compared to other drying methods.

It is a dry method of drying where reaction is not desirable.

There are wet method of drying like TEG.

It all depends on what is the aim of the drying process.
